Dyphene® 8318 is an oil-soluble, non-heat reactive alkyl phenolic novolak resin that imparts exceptional initial tack and tack retention to rubber compounds.  It is used extensively as a tackifier in tire compounds based on blends of NR, SBR and BR.

·          Imparts high initial tack in green rubber stock (auto-adhesion)

·          Retains a high level of tack even after extended exposure to high temperature and humidity.

·          Exhibits good compatibility.

·          Offers greater economy than many less expensive resins because lower loadings of DYPHENE® 8318 can yield equivalent tack.

·          Functions as a processing aid, aids dispersion of other compounding ingredients, reduces mixing viscosity.

·          Outperforms hydrocarbon resins for tack, tack retention and physical properties in many applications.

SUGGESTED USES:  Tackifying resin for building tack in tire carcass stocks using NR/SBR and NR/SBR/BR blends, and innerliner recipes containing chlorobutyl/SBR/NR blends.  Tackifying resin for tire cements, rubber-compounding applications that now use hydrocarbon resins.
